Lower extremity proprioceptive sensation in patients with early stage knee osteoarthritis: A comparative study

Knee OA causes pain and proprioceptive impairment. The body acts as a closed kinetic chain, and deformation on the knee cannot only affect the knee joint but also can affect the other joints. To assess the proprioception of lower extremity in early stage knee osteoarthritis compared with without knee osteoarthritis individuals. The study sample consisted of 26 adults with early stage knee osteoarthritis and 26 subjects without knee osteoarthritis individuals. Western Ontario and McMaster Universities Osteoarthritis Index was used for clinical disease severity. Visual Analogue Scale was used for pain severity. Proprioception (position and motion sense) was measured by isokinetic dynamometer. Western Ontario and McMaster Universities Osteoarthritis Index total score was 10.9 ± 5. Visual Analogue Scale scores during activity were found to be significantly higher than the scores at rest and night for both sides. Hip flexion and internal rotation joint position sense were significantly different between two groups (all p's
